SURFACE-TREATING DEVICE Application filed January 28, 1926. Serial No. 84,440.

This invention relates to surface treating devices generally, and has for its primary object to provide for a labor saving apparatus for this and other kindred purposes, including the cleaning, rubbing, scraping or wiping down of such surfaces, and, in its more par ticular adaptation for the treatment or cleaning of all kinds of windows, doors or the like, whether in plain or fancy, large or small, sliding, swinging or pivoted windows or doors, as well as windows or doors of different odd shapes, and those which are stationary in frames, such as store windows, doors and the like;

A still further object is the provision of an apparatus for simultaneous operation upon two opposite sides of an object, such as a window or the like, to be acted upon, together with two members to perform the desired actions and means to coordinate and synchronize the movements of the two operating members in action whereby the movements including the adjustments of one will be reproduced at the other. Thus as applied to the cleaning device proposed by my invention, both surfaces of windows may be cleaned at the same time, and usual labor reduced by at least one-half, and sliding sashes may be cleaned without the necessity of sitting on and swinging outwardly from the window sill and without the physical danger to the operator which these positions necessarily require in the usual cleaning of Windows.

A stillfurther object of my invention is the provision of a window cleaning apparatus including a cleaning member having cleaning and wiping elements along its opposite sides, which member is turnable to present either the cleaning or the wiping element against the glass, as well as to vary the angle of either thereof, and especially the wiping element, in its engagement with the glass. It is to be understood in this connection that both the wiping and cleaning elements may be of various forms, as for instance a cleaning cloth or brush and a wiping pad or rubber strip commonly known as a squeegee.

Various other objects and advantages of my present invention will be made plain in the course of the following description and in reference to the accompanying drawings which illustrate the invention and form a partof this specification and in which draw- 1ngs:

Referrin now to these figures, I have shown in the several instances of the application of my invention in practical use, a surface treating member which has a substantially flat body, provided along one longitudinal edge with a working element illustrated in the form of a brush and along its other longitudinal edge with a second working element in the form of a squeegee, or the like.

In the form of my invention illustrated in Figures 1 to 4 inclusive, the surface treating member of the form above described has its body constituted by a pair of plates secured to one another, the cleaning brush along one longitudinal edge being indicated at 16 and the squeegee or the like along the other longitudinal edge being indicated at 17. Moreover the body 15 is formed to provide a central longitudinal cylinder 18 to receive therethrough a guide rod preferably of the hollow form indicated at 19, and also preferably provided with a slot through its wall in which slot an inwardly projecting rib 20 of the body of the cleaning member extends, so as to thus constrain the cleaning member 15 to rotation with the'guide rod 19. The lower end of 19 is detachable as at 19 Fig. 2, so that the cleaning member with its rib 20 may be moved downwardly off of the guide rod in case repair or substitution becomes necessary. In this form of the invention it will be moreover noted that two cleaning members 15 and two guide rods 19 are employed in the spaced apart parallel relation shown the upper ends of the guide rods having rotatable bearings through brackets 21 adjacent to their upper ones and being provided above these brackets with bevel gears 22 securely fastened thereon.

The brackets 2i are securely held in connection with the inturned lower portions 23 of the depending sides 2 1- of a supporting frame, which also includes an upper horizontal body member 2-5 preferably in the form of a tube or pipe having around the central portion thereof a roller 26 preferably formed of wood or some similar material which will avoid defacement of the sash rails along which roller is moved in practice. Vl ithin the roller a bushing 27 seats loosely upon a sleeve 28 around the tube or pipe 25, the end portions of which sleeve project beyond opposite ends of the roller and have securely fastened thereon bevel gears 29 engaging the bevel gears 22 at the upper ends of the two guide rods 19 and thus constrained simultaneous rotation by virtue of their connection with the sleeve 28. 7 i

Rotatal is on the tube or pipe 25 above each of the guide rods 19, is a reel 30 controlled by a spring 31, one end of which is secured to the reel and the other end of which is secured to the tube 25. Upon each reel is cord or cable which is extended downwardly into the respective hollow guide rod .19 and is in connection at its lower end with the inwardly projecting rib 20 of the respective cleaning member 15, as most plainly seen by comparison of Figs. 2 and 4c In this way the cleaning members are placed under tension, adapted to simultaneously draw them upwardly along the guide rods at all times by virtue of the connection of the two reels with the sleeve 35 and by virtue of the connection of the two guide rods through the gears 22 and 29 and the sleeve 28, it is likewise obvious that any turning movement of the cleaning members will be synchronized, and further, when one of these members is moved to a slightly angular position in order to shift the angular position of either its cleaning element 16 or its wiping element 17 w th respect to the window glass, other cleaning member will be moved in the some degree, for the same purpose. This shifting of the cleaning members enables the elements carried thereby to pass over obstructions as in the case of fancy windowsembodying numbers of small panes of glass shown for instance in Figure 3, where the operation just referred to is indicated by the showing of the cleaning members in full and dotted lines, and it is obvious that this same shifting or swinging of the cleaning tllddQVlC/ to straddle a wlnv e a members permits dow sash when th undo-w cleaner as a whole is initially shifted downwardly upon the window and removed upwardly th refrom re spectively at the beginning and end of the cleaning operation.

The bearing brackets 21, may, as shown particularly in Figure 2, be also provided with inwardly projecting and upstanding portions 83 to support upright rollers 34 adapted to be positionedat oppositesidesof the upper rail of a window sash when the apparatus as a whole is shifted over the window to straddle the rail and to permit the roller 26 to roll thereon as the cleaning members are drawn back and forth across the window glass at the different levels permitted by virtue of the movement of the cleaning members lengthwise of the guide rods 19.

The reels 30 are preferably'rotatable and simultaneously rotatable upon the ends of a sleeve 35 around the tube 25, and eXtendin through the sleeve 28, which sleeve 35 is rotatably confined between the springs, and it is thus obvious that the sleeve 28 is in this way prevented from endwise movement while the'gears 29 at the same time confine between them the roller 26 and the latter in place.

It is possible moreover to do away with the reels 3O entirely as illustrated'in the construction shown in Fig. 9, where one of the sashes 36 is movably adjusted with respect to the other sash upon which the cleaning members are in operation, in lieu of the adjustment of the cleaning members vertically along the same sash in which the device operates, as in Figs. 1 to 4 inclusive. In Fig. 9 the guide tube of the supporting frame is seen at 37 with its depending and inturned ends having bearings at 38 for the upper portions of the guide rods 39. The upper ends of these guide rods have gears lOengaging gears 41 upon the opposite ends of a sleeve rotatable on the tube 87 and confined between said collars 42, the gears ll being mounted at opposite ends of an elongated sash engaging roller 43. In this form the cleaning members 44 are secured upon the lower ends effectively hold llll) of the'guide rods 39, for simultaneous rotation through the gears 40 and 41 and the device is operable in connection with one of the pair of sashes 36 by virtue of engagement of the roller 43 with the other sash.

It. is to be noted of the invention that several of the forms thereof, as herein described and illustrated, are adapted to clean both sides of the top and bottom sashes of a window from one edge of either of the sashes simultaneously, and with equal facility and efiiciency. V I

In Fig. 9 as w clusive, the cleaning members provided with cleaning elements at one side and wiping elements at the opposite side, are provided with side portions 45 extending in spaced parallel relation beyond one or both ends of the body of the cleaning member, and in each instance will be noted that the cleaning and wiping elements project continuously along the sides of the cleaning member and along such eX- tensions so that both the cleaning and wiping elements may project for some distance between overlapping sashes since in the use of this device it is necessary in its employment with upper and lower sashes that portions of the sashes overlap during such use.

As seen in Fig. 10, the cleaning members may be of the two part construction illustrated, the two parts being indicated at s5 and 46 connected along their longitudinal centers by a hinged joint, as at 4-7, whereby one part may be adjusted angularly with re spect to the other, and whereby to permit said parts to simultaneously or successively operate upon a window glass. This form of cleaning member is adapted to be mounted on the guide rods in any form of my device.

As seen in Fig. 10,1 may moreover provide the cleaning members with detachably locked side strips 48 carrying the cleaning element 49 and the wipin element 50 so as to provide for the renewal of these elements when 'nec essary. The strips 48 are normally secured in place by locking members 51.

As shown in Figs. 5, 6 and 7 my improved cleaning member indicated at 52 and constructed as previously described, may be applied to store windows and the like, lengthwise movable, and in rotatable relation, upon guide rod 53, which obviously may also be in telescoping sections whose upper end is carried in a bracket 54; having a turnable part 55 so that the rod with the cleaning member 52- may be elevated to the position shown in dotted lines in Fig. and the rod 53 placed over a hook 56 above the store window when not in use. The bracket portion 55 may support a reel 57 which preferably has a tension spring therein, from which a cord or cable 58 depends to the cleaning member 52, and the supporting bracket 54 including its part 55 has guide rollers 59 disposed within ,a guide track 60 above the store window, or

ell as in Figs. 1 to 4,'in-' this bracket may if so desired extend'throug'h a closable slotted opening above the store window and employed in connection with an inside cleaner constrained to movement with the outside cleaner in substantially the same manner as described in connection with the structure outlined in Figs. 1 to l inclusive or Figure 8. This apparatus, it will be noted,

that in this instance also the construction may be similar to that of Fig. 9 and may be intended for either the ordinary house windows or store windows, train car windows, etc. 1

lVhen employing one cleaning member in connection with a store window, as in Figure 5, instead. of placing the said cleaning member on a hook over the store window, as previously set forth, the lengthy guide rod can also be used to slide the cleaning member and its supporting bracket with guide rollers entirely out of the guide track in order that these parts may be entirely detached'and laid aside for using. This can obviously be accomplished by leaving at least'oneend of the guide or track open as indicated in Figure '5 in order that the guide rollers may be shifted into and out of the track. 7

As the device as a whole is of generally flat form, it is obviously possible to utilize bothinside and outside cleaning members in connection with store windows by providing the store window with an upper slot through which a device such as generally out...ned in Figure 1 may be shifted first in the horizontal position, and then brought down into effective vertical position against both sides of the window glass.

By substituting for the squeegee 17 of any other type of surface treating or working element such as a rubber or SCIRIQGT. rubbing or scraping operations may be performed with equal facility, such as the rubbing-or scraping down of dirt or other accumulations, or coatings from the surfaces to be treated or cleaned, and by moistening the brush with a liquid, such as water, on the one hand, the surface may be subjected to a scrubbing or washing action, or an oil orpaint, or other coating material, on the other hand, may be applied to the said surfaces.

With the above explanation, the effectiveness and efiiciency of the invention as well as its durability and inexpensive construction, and its ready adaptability to windows of various sizes and shapes, will be apparent and it will also be obvious from the description and the showing of the several modified forms that the invention is susceptible of various other modifications, as to structure as well as to function and use, within the spirit of the invention and the terms of the appended claims.
